Quality Parameters of PE–Pomace Based Membranes

Abstract

This paper presents the results of research on selected mechanical and physical properties of polyethylene membranes containing 50% of the plant fraction obtained as waste from an edible oil press. The produced biomembranes were characterized by low tensile strength (2.02–4.28 MPa). The addition of plant material will not adversely affect the barrier properties such as water vapor permeability or the contact angle. Additionally, there was a discoloration of the characteristics affecting the shrinkage of the membrane. The presence of the plant component clearly lowered the shrinkage of the material. This research is important and provides valuable knowledge on the possibilities of using plant waste and the direction of the potential application of the materials produced with their use.

Pomace from Oil Plants as a New Type of Raw Material for the Production of Environmentally Friendly Biocomposites

“…z o.o., Płock, Poland) and nigella, maize, and flax seeds, which were waste in the form of pomace after the oil pressing process. The biocomposite production method was carried out according to the procedure described by Betlej et al [33]. Plant pomace ground to a dusty fraction using a knife mill (OB-RPPD Sp.…”

“…This procedure made it possible to obtain a relatively homogeneous material. In the authors' previous work [33], the produced biocomposites were tested to characterize their physical and mechanical properties. The susceptibility of the produced biocomposites to fungal growth was also determined.…”
